Why is the scarlet cord significant in Rahab's story?

The scarlet cord that Rahab hung in her window serves as a profound symbol of salvation and faith in Christ’s redemptive work. This scarlet thread points to the blood of Christ as the means by which sins are atoned for. Just as the Israelites were instructed to mark their doors with the blood of a lamb during the Passover, Rahab's scarlet cord demonstrated her belief in the promises of God and His ability to deliver her from destruction. This theme of being redeemed by blood runs throughout scripture, culminating in the ultimate sacrifice of Jesus, confirming that His shed blood is the basis for our acceptance before God.
